CAP-ATTACH ER.

SPECIFICATION forming part of Letters Patent No. 487,562, dated December6, 1892. Application filed February 9, 1892. Serial No. 420,862- (Nomodel.)

To all whom it may concern:

Be it known that 1, CHARLES H. GRIFFIN, of Lake City, in the county ofHinsdale and State of Colorado, have invented certain new and usefulImprovements in Cap-Attachers; and I do hereby declare the following tobe afull, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to certain new and useful improvements incrimping or securing caps on fuses, and has for its object theproduction of simple and efficient means whereby a miner or other personcan readily attach a cap to a fuse so that the same will be securelyheld and be perfectly waterproof.

The invention consists, primarily, in a tool for firmly holding a cap ona fuse and having a pocket for holding a second tool for forming agroove or crease in the cap.

The invention further consists of a penknife having a circular openingextending therethrough and a pocket in one side and a blade having atooth projecting therefrom into said opening, a crimping-tool beingdesigned to be held in said pocket, substantially as hereinafter fullyset forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective of apocket-knife embodying my invention. Fig. 2 is a transverse sectionalview thereof. Fig. 3 is a side view. Fig. 4 is a detail perspective viewof a portion of the knife-blade.

Referring to the drawings, A designates a pocket-knife, and a a singleblade thereof. One side a of this knife is thickened and a longitudinalopening a is formed therein, the same constituting a pocket forreception of a crimping-tool. A circular hole or opening b, extendingtransversely through the knife-case is formed therein near thecontracted end thereof. This hole or opening is of size corresponding tothe fuse and the cap to be secured thereon. In the cutting-edge of bladea, adjacent to the inner end thereof, is formed a curved groove orrecess, in the center of which is a tooth b, which when the blade isclosed projects into the transverse hole or opening I).

In practice a miner or other person will first open blade to and thenafter placing a cap on the end of a fuse insert the former into openingI), after which the blade is closed down and pressure applied by thethumb of the left hand. The tooth b will effect a depression in the capand firmly hold the same on the fuse. The operator then forces the jawsof a crimping-tool down over the projecting portion of the cap adjacentto the inner edge thereof, and upon turning said crimping-tool in firstone direction and the other forms a continuous groove or crease entirelyaround the cap, and thus not only binds the latter in place, but alsorenders it waterproof, and prevents moisture, &c., from affecting thefulminate in the outer end of the cap. By opening the blade the securedcap can be removed and the crimping-tool placed in the pocket in theside of the knife until it is desired to again use the same.

The advantages of my invention are apparent. It is well known that bythe means now in use much annoyance is occasioned and valuable timeconsumed in trying to secure caps to fuses, whereas according to myinvention every miner can always have at hand a simple andhighly-efficient means for attaching the caps and protecting the latterfrom moisture.

Another and highly-important advantage attained by my invention is thatthe miner or operator always has conveniently at hand means for cuttingthe fuse, the blade of the knife being always used for this purpose.

I claim as my invention-- 1. The herein-described improved cap-attaoher,consisting of a pocket-knife having an opening therein and a bladeprovided with go a tooth projecting into said opening, substantially asset forth.

2. The herein-described improved cap-attacher, consisting of apocket-knife having a transverse opening therethrough, a blade havatooth projecting into said opening, and a side pocket for holding acrimping-tool for forming a groove or crease on said cap, as set forth.

In testimony whereof I have signed this too specification in thepresence of two subscribing witnesses.
